+Configuration Parameters
+------------------------
+The SED1330 driver supports the following parameters in config file:
+
+Device
+ Instead of using the direct output via port address (see Port), you
+ can use the parport device (/dev/parportX). The advantage over the
+ direct output via port address is that this works for non-root users
+ also. But it's a little bit slower. The modules ppdev.o, parport.o
+ and parport_pc.o must be loaded or compiled into the kernel.
+
+Port
+ Sets the port address of the parallel port. If this parameter is not
+ given, 0x378 is used. To use this direct output, the program that
+ uses the driver library has to be started with user 'root'.
+
+Width
+ Sets the horizontal size of the display. If this parameter is not
+ given, a default value of 320 pixels is used.
+
+Height
+ Sets the vertical size of the display. If this parameter is not
+ given, a default value of 240 pixels is used.
+
+UpsideDown
+ Rotates the display output by 180 degrees. This might be useful, if
+ the LCD is mounted upside-down.
+ Possible values: 'yes', 'no'
+ Default value: 'no'
+
+Invert
+ Inverts the display.
+ Possible values: 'yes', 'no'
+ Default value: 'no'
+
+AdjustTiming
+ To get a timing that is as accurate as possible, the drivers measure
+ the time for port commands (see: benchmark in syslog). You might
+ decrease or increase the time to wait after port commands with this
+ parameter. Normally, there is no need to change this parameter.
+ Possible values: -50 <= x <= 50
+ Default value: 0
+
+RefreshDisplay
+ Normally, most of the drivers do not update the whole display, but
+ only the areas that have changed since last update. So it might be,
+ that some faulty pixels would stay a longer time. To avoid this, the
+ plugin makes a complete refresh from time to time. This parameter
+ defines how often a complete refresh will be done.
+ e.g.: A value of 5 means, that the plugin will make a complete
+ refresh on every 5th update.
+ A value of 0 completely disables complete refreshs.
+ Possible values: 0 <= x <= 50
+ Default value: 5
+
+Wiring
+ Select the type of wiring your display is connected with.
+ Possible values: 'Original', 'PowerLCD', 'LCDProc', 'Tweakers',
+ 'YASEDW'
+ Default value: 'Original'
+
+OscillatorFrequency
+ Select the frequency the oscillator on your LCD board uses in kHz.
+ Possible values: 1000 <= x <= 15000)
+ Default value: 9600
+
+Interface
+ Select the interface mode your display is connected with.
+ Possible values: '6800', '8080'
+ Default value: '6800'
